Title: Correlation method for measuring target distance by using joint signal correlation and a device for the realizarion of the method
Inventor: SOROCHAN ANATOLII HRYHOROVYCH
IPC: G01S13/34
Filed: 2002-01-29
Abstract: The proposed correlation method for measuring target distance by using joint signal correlation differs in that, for enhancing measurement accuracy, the additional correlation processing and the following logarithmic amplification of the signals are used. The target distance is determined by the time delay (T) of the signal reflected from the target relative to the sounding signal. For the possibility to measure the said time delay, a signal is formed that is frequency-modulated by a sine-wave signal with a frequency of , with a modulation index of ,. The said frequency-modulated signal is divided into two component signals. The first component signal is used as a sounding signal and is emitted in the surrounding space. The second component signal is delayed relative to the first signal by a controlled time delay (e), shifted in frequency by a value of W, and multiplied with the reflected signal. From the output signal of the multiplier, the signal with frequency W is isolated that corresponds to the cross-correlation function of two multiplied signals. This signal is divided into two component signals. One of these component signals is delayed in time relative to the other signal, with a constant time delay, and multiplied with the said other signal. From the resulting signal, a sine-wave signal with a frequency of h is isolated and amplified by a logarithmic amplifier. The amplitude of the output signal of the logarithmic amplifier depends on the time delay difference - . If the value of the controlled time delay is i = 0 = , the amplitude of the output signal of the logarithmic amplifier would be equal to 0. The target distance is determined by the equation D = 0,5С,0, where C is the propagation velocity of the sounding signal.
